Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616882, here are decompositions:

43 + 31616839 = 31616882
109 + 31616773 = 31616882
211 + 31616671 = 31616882
313 + 31616569 = 31616882
373 + 31616509 = 31616882
463 + 31616419 = 31616882
523 + 31616359 = 31616882
601 + 31616281 = 31616882

Showing the first eight; more decompositions exist.
